I looked at pw's but each generation seemed so more software complex. Gen 2 was rx/tx either on any unit, then the ability to control camera triggering, etc and all sorts of options that seemed to go beyond what analog cameras need.
I thought 'do I need to fire lights from 200' or am I just sick of tripping over the sync cord?'
I realized that for 95% of my flash work that a radio trigger with a range of 5-50' and a few channels would be fine. Cactus gen 1 had short range , longer if you dangled a wire from the tx. Gen 2 has good range, 16 channls and fine battery life from my experience so far.
